Vim li cas koj yuav tsum tsav tsheb ntawm kev kub ceev

Ntau tus neeg tsav tsheb nkag siab tias cov peev txheej ntawm nws txoj haujlwm ncaj qha nyob ntawm tus qauv ntawm kev tsav tsheb thiab ua raws li cov cai rau kev khiav haujlwm ntawm lub tsheb. Ib qho ntawm cov khoom tseem ceeb yog lub cav. Hauv tsab xov xwm peb yuav qhia koj seb yuav tsum ceev npaum li cas nyob ntawm qhov xwm txheej ntawm txoj kev.

High engine ceev: ib txwm los tsis

Thaum xub thawj, nws yuav tsum tau muab sau tseg tias kev tsav tsheb ntawm qhov siab dhau thiab qis dhau yog fraught nrog qee yam kev phom sij. Tshaj li 4500 rpm cim ntawm lub tachometer (tus duab yog qhov nruab nrab thiab yuav txawv nyob ntawm lub cev muaj zog) lossis txav tus xub mus rau hauv cheeb tsam liab tuaj yeem ua rau cov txiaj ntsig hauv qab no:

1. Kev ua haujlwm ntawm lubrication thiab txias system yog nyob ntawm nws qhov txwv. Yog li ntawd, txawm tias ib lub tshuab hluav taws xob me me los yog qhov qhib qhov ntsuas kub tsis tiav tuaj yeem ua rau muaj cua sov.
2. Clogging ntawm lub lubrication raws, thiab ua ke nrog kev siv cov roj phem, qhov no ua rau "tshem" ntawm cov kab. Uas yav tom ntej yuav zoo ua rau ib tug tawg ntawm lub camshaft.

Nyob rau tib lub sijhawm, qis qis heev kuj tsis coj ib yam dab tsi zoo. Ntawm cov teeb meem tshwm sim ntawm kev tsav tsheb mus sij hawm ntev hauv hom no yog:

1. Roj tshaib plab. Kev tsav tsheb tsis tu ncua qis dua 2500 rpm yog txuam nrog cov khoom siv roj tsis zoo, uas yog nrog los ntawm kev nce ntxiv ntawm cov crankshaft liners. Lub lubrication tsis txaus ntawm cov khoom rub tawm ua rau overheating thiab jamming ntawm lub tshuab.
2. Cov tsos ntawm soot nyob rau hauv lub combustion chamber, clogging ntawm tswm ciab thiab nozzles.
3. Lub load ntawm lub camshaft, uas ua rau cov tsos ntawm lub khob ntawm lub piston pins.
4. Muaj kev txaus ntshai ntawm txoj kev vim qhov ua tsis tau ntawm kev nrawm nrawm yam tsis muaj kev poob qis.

Lub cav ua haujlwm hom yog suav tias yog qhov zoo tshaj plaws nyob rau hauv thaj tsam ntawm 2500-4500 rpm.

Cov yam ntxwv zoo ntawm kev hloov pauv siab

Nyob rau tib lub sijhawm, kev tsav tsheb ntev ntev 10-15 km ntawm kev kub ceev (75-90% ntawm qhov siab tshaj plaws) tso cai rau koj kom ntev lub neej ntawm lub cev muaj zog. Cov txiaj ntsig tshwj xeeb suav nrog:

1. Kev tshem tawm tas li tsim cov av nyob rau hauv lub combustion chamber.
2. Kev tiv thaiv ntawm piston nplhaib sticking. Ib tug loj npaum li cas ntawm soot clogs lub rings, uas nyob rau hauv lub kawg yuav ua tsis tau raws li lawv lub luag hauj lwm tseem ceeb - tiv thaiv cov roj los ntawm lub chamber. Qhov teeb meem ua rau muaj kev txo qis hauv compression, nce lubricant noj thiab cov tsos ntawm cov pa luam yeeb xiav los ntawm cov yeeb nkab tso pa.
3. evaporation ntawm cov khoom ntawm cov dej noo thiab cov roj av daig hauv cov roj. Qhov kub thiab txias tso cai rau koj tshem tawm cov khoom ntau dhau ntawm cov roj nplua nyeem. Txawm li cas los xij, thaum muaj emulsion tshwm sim, koj yuav tsum tsis txhob tig qhov muag tsis pom qhov teeb meem, tab sis tam sim ntawd hu rau qhov kev pab cuam kom nrhiav tau cov dej xau.

Nws yog ib qho tseem ceeb tshwj xeeb tshaj yog kom cia lub cav "sneeze" thaum tsav tsheb nyob rau hauv nroog thiab nyob deb li deb (5-7 km), sawv ntsug hauv kev sib tsoo.

Tom qab nyeem cov ntaub ntawv, nws pom tseeb tias nws yog ib qho tsim nyog yuav tsum tau tsav ntawm kev kub ceev tsuas yog ib ntus. Qhov no tso cai rau koj tshem tawm cov pa roj carbon deposits nyob rau hauv lub combustion chamber thiab tiv thaiv piston rings los ntawm sticking. Lub sijhawm so, koj yuav tsum ua raws li qhov nruab nrab ntawm 2500-4500 rpm.
